Reduced Blood Pressure (Current Hypertension Reports, December 2007)

This meta-analysis of 17 published studies from the medical literature (selected from over 100 published studies for their careful experimental design utilizing randomized controlled trials) reported on the effects of stress reduction techniques on elevated blood pressure in about 1000 subjects total.

The treatments employed included simple biofeedback, relaxation-assisted biofeedback, progressive muscle relaxation, stress management training, and the Transcendental Meditation program. The results of statistical analyses showed that none of the first 4 treatment approaches demonstrated statistically significant reductions in elevated blood pressure, while the Transcendental Meditation program showed both significant clinical and statistical reductions in blood pressure.
